Chairperson Nixt requested clarification that a drain field could be sited with at least one alternate. This would be known before a building permit is issued, with the PUD approved contingent upon resolution of the drain field or on -site sanitary system. City Engineer Jankowski replied this could be done by the Planning Commission. There would be substantial rights to the applicant once there is Council approval. Chairperson Nixt indicated the overall site plan will not change substantially as a result of the findings that may be obtained from additional soils testing. Mr. Walz stated they have been given the requirement to do additional testing to dig one 8 -foot test pit for every 10,000 square feet of septic system. The proposed septic system is only 2,400 square feet; the total square footage would be less than 10,000 square feet, so essentially they only need do to one test.
